Tube Amp is an audio effect plug-in that applies asymmetric tube triode overdrive usually found in single-tube microphone pre-amp boxes. The sound this plug-in produces varies from a mild "warm" overdrive to a fuzzy distortion. Beside that, Tube Amp includes a -6 dB/oct low-pass filter that is built-in into plug-in's valve modeling equation, and can be used to imitate a lower-quality tube triode.

Tube Amp also features all standard advanced Voxengo plug-in features like full multi-channel operation and built-in oversampling.

Features:

• Asymmetric tube triode overdrive.
• Multi-channel processing.
• Internal channel routing.
• Channel grouping.
• Mid/side processing.
• Up to 8x oversampling.
• 64-bit floating point processing.
• Preset manager.
• Undo/redo history.
• A/B comparisons.
• Contextual hint messages.
